It is big that there are distribution capacity, the disadvantage of product coil consistency difference, meanwhile, the coil in current smoothing choke is by artificial
It is wound on magnetic core manually, that is, haves the shortcomings that high production cost and production efficiency are low.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of novel smoothing choke, and internal coil uses
After the mode of single layer coiling is wound on magnetic core, it can be effectively reduced the distribution capacity of smoothing choke, help to improve product
Consistency, and using square shape frame shape magnetic core after, can by mechanization mode by coil winding on magnetic core, this
Sample one can be improved the production efficiency of smoothing choke, reduce the production cost of smoothing choke.
The novel smoothing choke of the utility model, including pedestal and the magnetic core being mounted on the base, magnetic core is square shape
Frame-shaped construction, be wound with coil on two sides of magnetic core, each coil is single layer structure, and two of each coil draw
Outlet extends through one of outlet hole on pedestal and extendes back for below pedestal, and exit and the pedestal of coil are fixed.
The novel smoothing choke of the utility model, wherein be provided on the upper surface of pedestal for the front side with magnetic core
The riser that Middle face offsets, the two sides of pedestal upper surface are provided with the positioning protrusion for being positioned to magnetic core, and magnetic core is embedding
It is located between riser and two positioning protrusion.
The novel smoothing choke of the utility model, wherein being provided on the inner wall of positioning protrusion upper end can match with magnetic core
Guiding is closed to facilitate magnetic core to be embedded into the arc guide surface between riser and two positioning protrusion.
The novel smoothing choke of the utility model, wherein the exit of coil passes through the epoxy that is filled at outlet hole
Resin is fixed with pedestal.
After coil inside the utility model is wound on magnetic core by the way of single layer coiling, filtering can be effectively reduced
The distribution capacity of choke coil helps to improve the consistency of product, and after the frame shape magnetic core of use square shape, can pass through machine
Or robotically mode so, can be improved the production efficiency of smoothing choke by coil winding on magnetic core, reduces filtering and grips
Flow the production cost of circle.
